Possible fields of application
The measuring variant "Measure kinematics" can be used to determine transformation-
relevant data for kinematic transformations that contain rotary axes (TRAORI, TCARR).
● Redetermination of swivel data sets
– Machine start-up
– Use of swivel-mounted workholders as TCARR
● Check of swivel data sets
– Service following collisions
– Checking the kinematics during the machining process
Kinematics with manual axes (manually adjustable rotary tables, swivel-mounted workholders)
can be measured in the same way as kinematics with NC-controlled rotary axes.
When starting
kinematic type, see the Programming Manual
CYCLE800). The measurement itself must be carried out without an active kinematic
transformation.
Requirements
The following requirements must be met in order to use CYCLE996 (Measure kinematics):
● Calibrated 3D probe (probe type 710).
● Mounted calibration sphere.
● Oriented tool carrier has been set up (general MD 18088:
$MN_MM_NUM_TOOL_CARRIER > 0)
● The basic geometry of the machine (X, Y, Z) is rectangular and referenced.
● The right angle refers to the workpiece spindle and should be preferably checked using a
test mandrel or with the
● Defined position of the rotary axes involved in the transformation.
● Defined traverse directions in compliance with the standard of all axes involved in the
transformation according to ISO 841-2001 and/or DIN 66217 (right-hand rule).
● Linear and rotary axes must have their optimum dynamic settings. This applies especially,
when the machine is to perform tool orientations during machining with active TRAORI.
● The probe must be calibrated precisely. The calibrated tool length of the probe is included
directly in the calculated vectors of the kinematics.
● When measuring, the measuring variant "Circling around the calibration sphere with
tracking of the switching direction" should be used.
Note
The vectors of the measured kinematics are only entered in the swivel data set if the
manufacturer's password is active. Kinematics can only be corrected when no persistent
transformation is active.
